How to get ADC/DMA working with LWIP TCP echo example project
I’m working with a NUCLEO-H723ZGI can generate a cube project with the ADC & DMA features working the way I want them to, but when I import the necessary code snippets into the LWIP TCP echo demo project & run on the same hardware the DMA fails on th...
Resolved! I find a bug in HAL_ETH_IRQHandler function. the function() skip all the if else，then return. have anyone met this question befor?
void HAL_ETH_IRQHandler(ETH_HandleTypeDef *heth){ /* Packet received */ if (__HAL_ETH_DMA_GET_IT(heth, ETH_DMACSR_RI)) { if (__HAL_ETH_DMA_GET_IT_SOURCE(heth, ETH_DMACIER_RIE)) {...}}I have met this question: this function cannot run to an...
Resolved! SD Card + RTOS on F7 processor won't work with D-Cache enabled! (My fix below)
*** EDIT ***Seems this was a memory issue rather than a D-Cache issue, the D-Cache option fixed it as a side effect!*** EDIT ***I have a project setup as follows:STM32F765IIKxRTOSSD Card on SDMMC1 configured as SD 4 bits Wide, DMA EnabledI followed t...
Bootloader in STM32 MCU.
What does it mean ->( the bootloader code begins to scan the USARTx_RX line pin, waiting to receive the 0x7F data frame: a start bit, 0x7F data bits, even parity bit and a stop bit.)?I'm totally confused understanding this line, how to configure it? ...
I have questions about STM32L496's DCMI capabilities. Is STM32L496 capable of recording a video and maybe even compressing a video? What's the maximum you can achieve with this MCU?
Hello ST community,I want to make a video recorder with STM32L496 and OV2640 camera module. The datasheet of the MCU(STM32L496) says this: "• 8- to 14-bit camera interface up to 32 MHz (black&white) or 10 MHz (color)" and this got me a little bit con...
Resolved! How access stm32 LWIP webserver by name
Hi,I've got an stm32H743 webserver with LWIP working ok on dhcp displaying data.Is it possible to alter the html file on the webserver to be able to access other similar webservers?e.g. Say I have 10 machines - each with one stm32 webserver attached ...
32F417: How to block USB_FS ISR from a shared resource (serial FLASH, on SPI)
I have a serial FLASH, a part of which implements a Windows file system (removable block device). Another part of the FLASH is for data logging etc usage.All this is working, but the ISR which implements the USB block device must be blocked out of th...
STSAFE-A crypto chip using X-cube/mbedTLS library example for microprocessor(arm)
Hi Everyone,We are using STSAFE-A110 chip for secure boot and secure firmware update for STM32G4 MCU, same we need to do for microprocessor(ARM7), we gone through the OpenSSL example provided by ST, we need STSAFE-A crypto chip using X-cube/mbedTLS l...
