Hi all i dont know what happen to the i2c line just after the address acknowledgement the SCL line goes LOW while SDA high and after that if i am sending data through data register I2C1_DR there is no response.Point to note that that if i initialize ...
Hi,I suddenly get this kind of interrupt in a code that was previously working perfectly. The instruction that makes this interrupt arise is *dst=*ptr. You can check below the function:void readHistoryFile(unsigned short * dst){ unsigned short * ptr...
I refer to the attachment. I am using a push button to power on a STM32F303. As soon as the push button is pushed a P channel FET is activated supplying voltage to the STM32F303. As soon as the STM32 starts it activates a pin which takes over activat...
In the stm32H750 reference munal, I can see the details of fdcan interrupt, mostly by config registers (FDCAN_ILS, FDCAN_ILE ), but I didn't see the illustration about which interrupt signal(like tx complete ) occurs in which interrupt line(line ...
Hello,Is it possible to use uart with dma, so that on idle we also get informed, so that we can read the rx data ?I found no example in hal cube for using UART with DMA in such "real life" scenario, only in simple full buffer fill - which is not prac...
I'm trying to teach myself C++ on STM32. Unfortunately the books on C++ I have and most websites I found do not mention interrupt handling. The websites where it was explained (embedded.com, stackexchange.com, etc) did it in a way I simply do not (y...
Hi sir/madam,In the datasheet of STM32H750XB 57th page J1 pin name is given as PH0-OSC-OUT and in 61st page the same pin is given as PH1-OSC-OUT. which do we need to consider?Datasheet: https://www.st.com/resource/en/datasheet/stm32h750ib.pdf
Here's the essence of what I have at the moment. I wonder why it does not enter DMATxComplete, I have tried with 128 and 30 buffer sizes...//****** dac.c **********// DAC_HandleTypeDef hdac1; DMA_HandleTypeDef hdma_dac_ch1; DMA_HandleTypeDef hdma_d...
I'm using STM32F405VGT6 to output sine wave by using its dac.After every output sample,which is triggerd by timer, dac's data holding register 'DAC_DHR12R2' is not holding the data and is reset to zero.So the output wave is something like sine wave m...
