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 January 05, 2015 at 08:33My project involves using a STM32L152 device as a SPI master that receives data from a slave (digital accelerometer). When I look at the SPI signals through a scope, I notice that the incoming SPI data is being int...
Posted on January 04, 2015 at 17:09hi, STM32F103C8T6 Minimum Board after system reset NRST or power reset not run(blink LED). After core reset in ST-Link utility window MCU runs to next hardware button reset. Can any help me please #reset-stm32
Posted on January 04, 2015 at 09:22Dear friends.My platform is STM32F429Discovery.I encountered whit Hard Fault error. I used the code of Joseph Yiu to track the place where error occurs. It is in the portasm_cm4.s (FreeRTOS). ldr r0, [r1]r1=0x03FF...
Posted on January 03, 2015 at 13:50Hello all, I just began working on an old project which had some problems that had not been solved, of which I did manage to pinpoint (in relative terms) the source. Developing platform: Keil uv4 Chip: ...
Posted on January 04, 2015 at 13:09We are building a digital LED buck converter with slope compensation as described AN4885 High brightness LED dimming using the STM32F334 Discovery kit.The discovery kit application uses the DAC to generate a 250 kH...
Posted on December 28, 2014 at 22:41Does anyone know if it's possible to enable the DAC without having it drive the corresponding output pin (PA4 on STM32F301 in my case)? I want to use it as a reference for the internal comparator, but unfortunatel...
