(Sorry, I am not a pro and the Google search AI is braindead.)I am just nerding out over FERDS at the moment and want to build a SMPS using them. 

Hi, I cannot manage to receive the bytes on UART protocol on an STM32U0 when using the STLINK-V3MINIE.The RX works properly (I can send data to the PC), so the pins are not swapped. The Vref of STLINK is 3V3, and the STLINK measures it correctly. Moreover, I can successfully program the U0 using the STLINK so I think both devices are in good shape.The UART baud rate is 115200 b/s. I have attached an oscilloscope to observe the signal. When NOT connected to the MCU, the TX signal is clear as expected (0V as low and 3V3 as high). If I connect it the MCU, the signal is still very clear and sharp but reduced (the "low" level is about 1.65V and the high level is 3V3). The schematic is the most straightforward: no components between the STLINK and the MCU.The firmware on STLINK is the V3J17M10.Currently, I have solved it using another USB-serial converter (CP2102) and it works flawlessly in both directions, using interrupts, DMA and

Hi,I have developed an application for the STM32C562RET microcontroller that wakes up from standby mode, initially based on an example provided by ST. The non-FreeRTOS version of this application works fine (though there is a minor wake-up issue that is fixable). Subsequently, I created a FreeRTOS version of the same application that starts a task, and when the user presses a button, the vTaskEndScheduler() function is called to terminate FreeRTOS, which in turn calls void vPortEndScheduler(void) where the wake-up code is implemented. void vPortEndScheduler(void) { HAL_RTC_WAKEUP_Start(HAL_RTC_WAKEUP_IT_ENABLE); LL_PWR_ClearFlag_SB(); HAL_PWR_EnterStandbyMode(); } Despite the fact

As I understand, the TSSOP20 version needs an external oscillator instead of a 8MHz crystal connected directly to the MCU pins. Is that correct?I'm asking because I have seen a board on AliExpress using this same processor with a 8MHz crystal.

 Hi~ My board gets stuck at the kernel stage during boot. I've referred to numerous related posts but failed to resolve the issue.The boot file versions I use are OP-TEE 4.0, U-Boot 2023.10 and Linux 6.6.116.The official device tree I referenced is stm32mp157f-ed1.I have attached the boot logs, hardware schematic and device tree files. Please help analyze the root cause of the problem.   stm32f7-i2c i2c@5c002000: pinctrl_select_state_full: pinctrl_config_one: err=-19​    [ 1.741795] arm-scmi firmware:scmi: SCMI Protocol v2.0 'ST:' Firmware version 0x0 [ 1.748959] DEBUG: SCMI CLOCK PROBE STARTED! sdev name: scmi_dev.2 I/TC: SCMI-CLOCK: Reporting 34 clocks to Linux I/TC: SCMI-FW: ETZPC ID 2 DENIED for Non-Secure world!

Hi, I have bought STM32H743VGT6 and want to make bootloader and application. The issue is that its memory layout is confusing. In documentation and generated application I see/assume flash memory is:0x8000000 size 0x80000 (512kb bank1?) // bootloader 0x8100000 size 0x80000 (512kb bank2?) // applicationBut when I try to write to 0x8100000 I get "Error occured during memory writing!". Instead I can write to0x8000000 size 0x100000 (1024kb)Does this mean I have only Bank1, but no Bank2? Can I still do bootloader which is on Bank1 and writes to flash on same Bank in different sector? How can it be that I have only one Bank?..

Hi all,Hoping this is this right subsection to post the following question...I'm reading the STPD01 datasheet and it states its available I2C addresses : 4, 5, 6, and 7.Reading to general I2C documentation, it seems that these addresses are reserved to I2C HS-Mode. So, is STPD01 an HS-Mode controller or a regular (100kHz) device? Links:- https://www.ti.com/content/dam/videos/external-videos/en-us/8/3816841626001/6241024036001.mp4/subassets/adcs-introduction-to-i2c-reserved-addresses-presentation.pdf- https://i2cdevices.org/addresses-

Hello,I am working on a custom FOC Inverter Board.  I am trying to assign the pins for current sensing, but I keep getting warnings.  I am using an STM32G431CBT6 MCU, and I completed all the other pin assignments without issue.  Here is the Current Sensing information:"Three Shunt AmplifiedCurrents using External Op-Amps"CURRENT_AMPL_U -> Assigned to PB14 ADC1_IN5CURRENT_AMPL_V -> Assigned to PB12 ADC1_IN11CURRENT_AMPL_W -> Assigned to PB11 ADC12_IN14It looks OK in the board designer application with no warnings, but when I try to generate the project in Motor Control Workbench, it gives me the following errors: 

Hi,I already tried to search for previous threads that could help me (like this one), sadly without success.I'm currently studying the ADC peripheral on STM32F3DISCOVERY from the reference manual. I started writing a simple program to measure a tension on PA0. It all works flawlessly until the ADC samples the value on PA0, stores it in the Data Register and raises EOC. From the manual:"The ADC sets the EOC flag as soon as a new regular conversion data is available in theADCx_DR register. An interrupt can be generated if bit EOCIE is set. EOC flag is cleared bythe software either by writing 1 to it or by reading ADCx_DR." (page 347, Section 15.3.23).The loop part of my code is the following (I already configured the ADC for single conversion mode, L[3:0] = 0

I am currently using TouchGFX to develop a project. How can I independently control GPU2D to draw graphics on a dynamic bitmap without affecting the TouchGFX display? I have already obtained the NeoChromSDK, but the examples in the NeoChromSDK all use GPU2D independently as well.  I can draw with GPU2D if touchgfx not in use,But once I display them both, screen got glitched.

  Hello everyone, I am new to STM32 development and I am working with the STM32H7A3ZIT6 microcontroller. I need to interface it with a BiSS-C encoder/sensor. I would like to know: Is there any ready-made or full BiSS-C communication library available for STM32? Does STM32CubeMX / HAL provide any support for BiSS-C? If no full library is available, what is the recommended way to implement BiSS-C on STM32H7A3ZIT6? Can BiSS-C be implemented using SPI, timer, DMA, or GPIO bit-banging on this MCU? Any example code, application note, or guidance would be very helpful. Thank you.

Hi.I'm trying a simple ping application with my board that contains the H743 microcontroller. I am following the instructions in Adam Berlinger's example. But I can't get ping. I connect my computer to my board via ethernet switch. My computer's IP is 192.168.2.5. But it can't reach to my board. When I try to send UDP packet, I can see the Ip adresses of target and destination(via WireShark software). But I can't see the "Hello UDP message!\n\r". IPs are manually setted. H7 board and computer connected via ethernet switch hub. I added a breakpoint to "void ETH_IRQHandler(void)". After the initial power-on, the system reaches the breakpoint twice even when there is no ping command on the Ethernet port. But when i send ping commands, nothing happens. I can reset LAN8742A PHY via GPIO.  /* Initialize all configured peripherals */ MX_GPIO_Init(); /* USER CODE BEGIN 2 */ HAL_GPIO_WritePin(ETH_RESET_GP

If I have only 5V input. what to do with the FB pin?

Is there a standard list of SB's? I cannot for the life of me figure out the SB's on the STM32F723E-DISCO, and none of the manuals mention anything about them other than if open is on or off. I am specifically trying to use the debugger for my custom PCB based off the same MCU. Any help would be greatly appreciated!
