STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
Posted on September 20, 2016 at 09:42 Hello all, im going to parse json string in my project, i found jansson library for keil, there is an example for cortex-m3 that run just fine in simulator. but the problem is when run the code on stm32f1...
Posted on November 27, 2017 at 15:24I am using the SAI in my custom F7 board in slave RX mode. I am having trouble receiving SD from the audio codec. In debugging this issue I noticed that the HAL code generated by CubeMX does not have a configurati...
Posted on December 05, 2017 at 15:34I have a custom F7 board configured as a USB HID device (using CubeMX generated code) that won't enumerate with my PC host. However, if I pull BOOT0 high, it will enumerate as a 'STM Device in DFU Mode'. So I assu...
Posted on December 04, 2017 at 10:55I am working with the stm32f7 microcontroller and I have 2 projects, a bootloader project and an application project. The bootloader resides in the beginning of the flash memory and the application resides in the ...
Posted on December 05, 2017 at 11:16I try to make better schematics about stm32f407vg microprocessor.Is these power connections OK?#schematics
Posted on December 05, 2017 at 09:50I'm developing an application based on STM32L4 on a custom board. Program is running fine but I noticed that sometimes (maybe once after four days working) device is reseted. In order to find the reason of this re...
Posted on November 30, 2017 at 11:49Hello all I'm working on STM32L152RE nucleo board. I ain't able to integrate Timer in low power mode .so is it possible to work with timer and low power mode in STM32L152RE simultaneously?If yes, which timer is ...
Posted on November 20, 2017 at 22:35On a Nucleo board, is it as simple as pulling the 0 ohm resistor off SB45, and connecting a coin cell [something like a CR1220] to pin33 [VBAT] and ground, in order to have battery backup for the RTC registers?
Posted on December 05, 2017 at 01:15I was wondering if there was any explanation for having several Port E pins (10-13) set to Input (00), and pin E11 is staying high even though there is nothing connected to it. I have tried setting the GPIOE->PUP...
Posted on December 02, 2017 at 18:59HI I've been trying to get an SD card working in 1bit mode using the SDIO peripheral. I am failing, and would appreciate some help. I'm on a Nucel401RE using STM32Cube_FW_F4V1.180.0The pin configuration is below. ...
