Hello, We have been trying to read 12 bytes of data on EC25 from stm32 controller.On the first run, data is transmitted by stm32 in slave trasmit mode and EC25 is reading the data correctly. We are able to capture the read log on EC25[Master read mod...
I use 2 board for generate pulse and count pulse.I generate pulses with 4Hz frequency by first board and print number of each pulse also when I press button pulse production stops and then after 20ms products a another pulse(I things micro in second ...
Hi,In stm32f051, iwdg is not working, I think.After enable iwdg, encounter the while(1); loop , reset is not issued.NRST pin is connected to RC reset circuit.BRPaul
In SPIx_I2SPR, I2SDIV=1 is probably fine as long as ODD is kept 0.https://community.st.com/s/question/0D50X00009XkYmHSAV/f2f4-i2s-extclockThis constraint probably unnecessary puts pressure onto using higher than necessary I2S clock, and restricts cer...
In the single-port DMA, CCR.EN when set, it locks most of the registers, including all other fields of the CCR register itself.Moreover, EN is not autocleared when single-transfer is complete. This is not documented clearly anywhere.These two things ...
I'm struggling to understand why I'm seeing a huge performance hit by slightly changing code in a loop. I narrowed down the problem to a manageable code size, and I'm hoping someone here can suggest how to investigate and resolve my issue.I'm using a...
Hi All,I am using STM32F427ZIT6 MCU for one project. I connected SPI4 for two different interfaces by mistake. Pins 1,4,5 for one interface and pins 64,65,66,67 for one interface.I want both the devices working simultaneously. Is there any solution f...
Apparent bug in the header file? Best I can tell, the Interrupt Priority Mask Table that follows appears correct?
I'm using STM32F779II With a microsd card. That is clocked at 48MHz.When writing to the sdcard as a block, I get HAL_TimeOut, using that function: err = HAL_SD_WriteBlocks(&sd_handle, (uint8_t *)src, block_num, num_blocks, 6000);After writing I wait ...
