Question
Bad C Code in conjunction with STM32-MAT/TARGET V4.4.1
Posted on February 13, 2017 at 15:59
Dear STM32 supporters,
I recently updated to V4.4.1 of the MATLAB/Simulink library 'STM32-MAT/Target'. (See also the resolved question at
). I am using MATLAB R2016b.The code generation works fine. But the generated C codes has misktakes:
H-File:
/* ADC1 Regular channel Converted value DMA buffer */
extern uint16_t ADC1_RegularConvertedValue[0];�?�?An Array with the size of 0 is invalid. I had expected here the value 2 as my model also shows 'Nb of regular channels: 2'.
The code tries to access invalid array elements (each element is invalid):
C-File:
/* ADC1 Regular channel DMA buffer pointer initialization*/
ADC1_DmaBuff = &ADC1_RegularConvertedValue[0];
/* ADC1 Regular channel DMA Half transfer complete buffer pointer initialization*/
ADC1_DmaHalf = &ADC1_RegularConvertedValue[0];
/* ADC1 Regular channel DMA Full transfer complete buffer pointer initialization*/
ADC1_DmaFull = &ADC1_RegularConvertedValue[0/2 - 1];�?�?�?�?�?�?0/2-1=-1 is also strange!
Can you confirm this?
Is this an issue of MAT/Target V4.4.1?
