Hi Team,I am using Smart battery in my product. While reading the battery voltage or current, that value was unexpected. while debugging the clock signal was not correct. In smbus line three devices were connected, Host(mcu (stm32h7)), Master(Battery...
Hello, hope you are all well!I am new in this field. I am trying to do a project where I have to program a board.The board contains the following: a) a STM32L4 module and b) an external chip.The board that I am using for debugging is a Discovery boar...
Hello,I’m currently developping an image software on a nucleo h743zi2 with mbed.I have to deal with 10b VGA images coming from the DMA & DCMI interface. to store it, I need a RAM bigger than 640 x 480 x 2 bytes = 614.400 bytes.After looking at th spe...
Hello, working with STM32H753 and wanted to know the maximum gpio speed it could achieve. Have achieved only 50MHz using TIM with PWM .Also can it take input of 30MHz 8-bit parallel data? Is there any specific functionality required to achieve high s...
I am trying to communicate with a peripheral device through SPI interface using the HAL SPI library functions. But the function is not working properly. It is getting stuck inside the HAL_Delay function. HAL_SPI_Transmit function just executes an emp...
Hi guys I am using the stm32h753zi MCU and writing my own drivers to use the WS2812B led strip.It uses a PWM to determine how much of the RGB you want. I got the PWM part down and the OPM done, the problem is that I want to send let say a duty cycle ...
Light up the LED in 30 seconds with 3 methods.1. Install IDEStep 0. Prepare HardwareThe hardware used in this experience is ST's development board NUCLEO-F411RE, and the development board number is MB1136. If you don’t have this board, you can use ...
I declare this two variable globallyuint8_t data_rcv_flg[1] = { 0 }; /* To avoid reuse of data */ uint8_t run[1] = { 0 }; I use this variable here:MODEM_ConfigTypeDef modem_cfg; modem_cfg.buff = data; modem_cfg.rcv_flag = data_rcv_flg; PROTOCOL_Con...
