Hey. I would like some clarification regarding writing to Flash memory. Specificially, 4 bytes (float values).I have the following code: void FLASH_write_single_float(uint32_t address, float data_to_send) { if (address < 0x080E0000 || address > ...
Hi Folks, I'm working on pattern generation on GPIO pins and I've done it successfully using bare-metal programming approach. I used TIM1 to trigger DMA2 to take data from a buffer and send it GPIOA->BSRR. But when I try to change the timer from TIM...
Hello, on an STM32F407 I am experiencing a Flash Erase/Write error. The odd things is that it happen only the first time after boot, the following times after the error I can write with no errors. But, if I erase and write in the Init phase, bef...
Hello everyone,I'm configuring a STM32L0 core board to connect to a module using AT commandAll the commands work fine but when I get to a given command (AT+MSG="123456"\r\n), they work only the first time and the second time it only sends ATfor examp...
We are using STM32F105VCT micro in our product from many years.In the recent hardwares, we have seen that input logic level is changing only with 200mv change.When the input voltage to any port pin is crossing 1.5 we are seeing as logic level 1, when...

HI everybody,Using the STM32F103 series, I was able to configure a single channel with DMA and get ADC data, but I was unable to analyze any data or do any while loop calculations for the moment. I simply increased a variable to see if it was updatin...
Hello.We are using PA3 pin as input with pin pull up enabled.Power consumption of the board is around 36 microamps when pin is not connected to ground.But when we connect PA3 to ground we have current increase to 74 microamps.I think that we have som...
I use timer with input capture mode, to be able to measure time period of an optical encoder pulse. I experienced that measured value rarely is twice as the expected one. I tried with different timer prescaler values, but same problem remained. Suspe...
