Hello!. I Have two firmwares: bootloader and application. MCU is STM32L031K6U6First launched bootloader checking backdoor pin and launching appliction or starting firmware update process. If need just start firmware all work fine (bootloader don't ch...
Hello,I use DMA UART on Rx.but I get interrupts on half complete and full complete.is it possible to get interrupt earlier? when I get "\n" char?maybe the best way to mange is to use circular DMA, and when the half complete interrupt is fired, save t...
I am using an STM32G4. I want to output PWM from a timer channel on one pin (call it pin A) and have a GPIO output on another (pin B). Then I want to be able to switch the functions on the two pins so that pin A is now a GPIO output and pin B is the...
I have an STM32L031F6 (custom) board. Using Jlink flashing tool we are trying to program the device but when we are trying to erase the board, we are getting the following error.Erasing device (STM32L031F6)...****** Error: Timeout while checking targ...
This pertains to the Nucleo F446RE development board.I'm beginning to explore DMA and want to use it to drive a sine wave through DAC1. The code to "manually" feed the data works fine and I get the expected sine fine, I can see that on scope.So I'm n...
Greetings,I need to provide PWM signals for 36 and 34 Outputs. Both the cases have been described under. Kindly note that all the outputs are independently operated. I need to know if STM32G474 can address to the job?CASE 1:These are the list of 6 PW...
hi, why WWDG_IRQHandler is not waking up, it configured even though not waking up.please guide me and show me asample program for WWDG.thanks
Hello, I am using hterm with stm32f4 to send and receive data. However, when receiving data streams, hterm hangs. I have tried everything but do not know what the problem is. Please help if you can.Thank you in advance
Hi Guys, I am using TIM3 with 4 channels to generate a PWM signal for my motors. Right now there is no phase difference between the PWMs, but now there is a requirement where I need to generate a Phase difference like shown in the figure below I was ...
Hi, I was testing UART communication using F446RE Nucleo Board. I was sending data to COM port by a python program running in PC and trying the receive to same data.ser.write(serial.to_bytes([1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15])) print...
