port sqlite in STM H7

Hi,I want to port sqlite in STM H7 MCU. Database will reside in SD Card (FATFS). Is there any example available for this??

Program Arduino with USB CDC as VirtualCOM

Is there anyway to upload some firmware to the STM32 that makes it act as a "serial passthrough", receiving the serial data from the computer from the virtual COM port, then writing it to a UART, which is connected to pins 0 and 1 on the Mega. The ba...

Issue in using "HAL_UART_Transmit" in FreeRTOS-MPU Usermode task

I am using FreeRTOS-MPU port with STM32F412. I have taken example which is given in STM32CubeF4 sdk package (STM32Cube FW_F4 V1.24.1\Projects\STM32F412G-Discovery\Applications\FreeRTOS\FreeRTOS_MPU).All things are working fine but I am not able to fi...

Where can I find documentation for the HAL drivers for a STM32 MCU?

I'm trying to use STM32CubeIDE to develop some code on a STM32F031C6 MCU. I've configured the peripherals I want to use but so far the only way I can use the HAL drivers is by reverse engineering each function. There's got to be some kind of docume...

Resolved! Does Ethernet communication require the use of the MPU?

Hi, in all the example code I've found related to using FreeRTOS and LwIP and performing Ethernet related tasks the MPU is always used to protect the Ethernet DMA. Why is this the case and what could go wrong if the MPU is not used?Thanks,Doug

previously working UART interrupt not working when FreeRTOS preemptive task scheduling enabled

Hi, I have some working code for STM32F746ZG that has a UART command line interface and FreeRTOS. It uses the "HAL_UART_Receive_IT" function and then waits for "HAL_UART_RxCpltCallback" function to set an OS flag when a character is received. When I ...

Does FreeRTOS need to use preemptive task scheduling when combined with LwIP for proper Ethernet operation?

Hi, I'm just wondering if it's a requirement for FreeRTOS to use preemptive task scheduling when combined with LwIP for proper Ethernet communications. In the examples available with the STM32F7 Cube firmware all of the examples have preemptive task ...

Problem with STM32F205 BOOTLOADER

Hello,i have one problem with bootloader application. I used STM32F205 microcontrollerMy Bootloader SW starts to 0x0800000 address and my application starts to 0x08010000 address.Application is correctly written but it's not possible to jump on the 0...

USB pendrive is not initialized

I'm trying read/write files from Fat FS from usb pendrive throught my custom board using STM32F7 MCU and I have a initialitzation problem in some usb pendrive. I was testing with 2 diferent usb pendrive, one with 2Gb and the other 32Gb. The 2Gb pendr...
