Hi,to clear bit 7 in port C I used a write to the BRR register: GPIOC->BRR = 0x00000080. Did not clear bit 7. A write to BSRR works: GPIOC->BSRR = 0x00800000. Is the BRR register not implemented (seems kind of redundant anyway with having BSRR)...
I trying to find information on the system information block of the stm32l073rb, specifically the address of the vrefint calibration value. I've looked in the ref manual, the data sheet and the L0 HAL docs and have come up empty. Please show me how s...
I am using STM32F407 and STM32F103 MCU.I want to implement it with FOTA(Firmware Over The Air).What I can do.Is there any solution available please let me know.Kundan Kushwah
Dear Members,Can I use SIM900 without SIM card for init code ?Does it support 3G ?Thanks
My goal is to have a timer that triggers an interrupt at 1kHz and for that to call a few lines of code that starts a HAL_SPI_TransmitReceive_DMA call (or possibly more than one on different SPI buses). Once the SPI calls are made, it enters a while l...
Hello, I'm trying to use two identical stm32f4 boards to synchronize tick of one with respect to other.I'm using can to using can protocol for communication in Interrupt mode.So the Master is supposed to be always running and the slave when powers up...
Hello,I apologize if I did not find a suitable place to raise this issue.The new site template is improved, but there's a problem with its menu. On some pages of the website, when scrolling the page up and down, suddenly get a fix menu on the page, w...

Hey,I configured the stm32h743 to transfer data with sai2 and read the same data with sai1. Sai2 is in IT mode and works fine (checked it with a logic analyzer).The SAI2 is totally working in IT mode, but when I put it in DMA mode i only receive 0's....
Posted on August 17, 2017 at 13:48Hello, I tried the example 'FDCAN_Com_polling' on STM32H743I-EVAL, it worked like it should be.Then I separated the example code into TX part and RX part, made one of my STM32H743I-EVAL board as TX and another as...
