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 July 28, 2016 at 14:35When I compile the sample firmware for the NUCLEO-L476RG board using the provided project for the Keil IDE, I get the following error:STM32F4xx-MEMSMIC1\STM32L476-MEMSMIC1.axf: Error: L6218E: Undefined symbol APBPresc...
Posted on July 28, 2016 at 11:09Hello all, STM32F1xx ref. manual (RM0041) states different USART receiver tolerances to clock deviation depending on whether DIV_Fraction is zero or not (see attachment). Could someone please explain to me why fractio...
Posted on July 26, 2016 at 03:17We are currently using the USB audio with the STM32F4, which works well. However, the power consumption of 40mA is something that we want to improve. Would change to STM32L4 help the situation? Our use is just using...
Posted on July 19, 2016 at 09:36Hi my name is Etienne, I am new to microcontrollers and I'm still banging my head against the wall. I would like to run a simple USART printf function to get things going. To keep it short, Ive got a Nucleo F103...

Posted on October 23, 2015 at 14:25 I've a custom board with STM32F073C8 SOC [1] and Spansion flash memory [2] among other things. This external flash memory (Spansion) on board is connected to STM32F072C8 over SPI bus. I'm planning to use STM32 ...
Posted on July 25, 2016 at 18:15What would you recommend for an IDE programming for the STM32F437VIT6 with the ST-LINK/V2?I will be doing some basic things like SPI communcation, I2C, and toggling pins.Any thoughts on Atollic? Something else that m...
Posted on July 28, 2016 at 05:41 Hi. I've compiled a couple very simple working programs for my 446Nucleo board using CubeMX. I'm having trouble when I want to use functions found in the SPL, like RCC_GetClocksFreq. Is there a loose tran...
Posted on July 25, 2016 at 18:12Hello everyone.1.) We are going to be using the STM32F437VIT6 in a new design and would like to get going with some firmware development. Is there a development / demo board that you guys could recommend that has the...
Posted on July 27, 2016 at 05:17The processor is an STM32F373VCT6. I am software triggering SDADC1 every second using this call each time: HAL_SDADC_InjectedStart_DMA( &hsdadc1, (uint32_t *)SDADC1_Data, SDADC1_Data_Size ); The DMA buffer size has ...
