Hi team,
Here's an issue from the customer may need your help:
In the hal code generator software, the user can set the length of the Mibspi's data transmission, which is the length of the group. But what should customers do if they want to dynamically modify the length of each data sent during use?
Set length to 16 and modify the tms570_mibspiSetU8Data function when sending data. The customer wants to be able to send 4 bytes of data when calling this function. However, the waveform captured by the oscilloscope found that the data sent was always 16 bytes.
void tms570_mibspiSetU8Data(mibspiBASE_t *mibspi, uint32 group, uint8 * data,uint32_t u32DataLen)
{
mibspiRAM_t *ram = (mibspi == mibspiREG1) ? mibspiRAM1 : ((mibspi == mibspiREG3) ? mibspiRAM3 : mibspiRAM5);
uint32 start = (mibspi->TGCTRL[group] >> 8U) & 0xFFU;
uint32 end = (group == 7U) ? (((mibspi->LTGPEND & 0x00007F00U) >> 8U) + 1U) : ((mibspi->TGCTRL[group+1U] >> 8U) & 0xFFU);
if (end == 0U)
{
end = 128U;
}
if(end > start + u32DataLen)
{
end = start + u32DataLen;
}
while (start < end)
{
/*SAFETYMCUSW 45 D MR:21.1 <APPROVED> "Valid non NULL input parameters are only allowed in this driver" */
ram->tx[start].data = *data;
/*SAFETYMCUSW 567 S MR:17.1,17.4 <APPROVED> "Pointer increment needed" */
data++;
start++;
}
}
Could you help check this case? Thanks.
Best Regards,
Cherry
