I have connected in port B(SWD Interface), i tried both powering modes with no jumpers and with 1,2,3 jumper.i am getting a error note $00000007 cannot enter into debug mode.what may be the issue.?
I use the UART on a STM32F7 with DMA. Is there any way to detect a stop of an incoming transmission with an interrupt e.g. with HAL_UART_ErrorCallback? If I expect too many characters or not all characters are transmitted?
On H7 MCU, waht is the minimum freq of SCK on SPI block? I try to connect a ADC with max SCK 3.2Mhz to H7's SPI port.
We have implemented a single ended ADC input to measure a voltage on our board. At low temperatures there is a significant error in the measurement.Going from +20C to -20C, the value we get from the ADC is ~92mV (114 counts) lower than it should be. ...
The STM32G4 series offers dithering to enhance the PWM ratio. My question is, if dithering can be used on ALL the compare channels of the same timer?Specifically, we generate a center-aligned PWM with two output compare channels 180° shifted. CCR1 an...
Scenario – Currently I am using STM32F303CBxx as my slave and an Infineon microcontroller as a master. The communication takes place via SPI with the clock frequency as high as 1.985 MHz (approx.). The master and slave are inside a closed metal compa...
I am using STM32L4R9 Discovery board with 2 MB external PSRAM and OV9655 camera (DM-CAM130). The demo code I've got has example of VGA camera configuration, however it requires a framebuffer too large to fit inside RAM. When I am choosing PSRAM, I am...
I am using a STM32F407 processor
I have a weight cell which replies to specific frames over RS485 (cell contains its own communication protocol). Manufacturer has a software to test the cell so I connect it to my pc using a RS485 to USB converter and I am able to connect to the cell...
