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...
DS12589 Rev 1 (for G431) and DS12288 Rev 1 (for G474) both states in Section 3.5 that SRAM2 can be accessed by CM4 core through System Bus or through the I-Code/D-Code bus. However, Figure 2 "Multi-AHB bus matrix" suggests that SRAM is only accessibl...
Hi,I am working on B-L475E-IOT01A2 which is a STM32L475 series Discovery IoT kit and has an ARM M4 cortex. It has two banks of FLASH Memory of size 512 KB each. I am implementing two applications along with a bootloader and all of them are stored in ...
i config TIM with PWM , and insert deadtime , i found the first deadtime is longer than later , this why behave so ?
Hi,I am trying to use an e-paper and a STM32L053C8 microcontroller.When i use the display in the first cicle, all works fine, but after wake up from stop mode, the display not works. Maybe the SPI interface not start well or i am doing somthing wrong...
Hallo.I want to use OSPI to feed an external DAC with data.Data shall be transfered through DMA from memory to OSPI. Eight bits and OSPI-CLK shall be used.In the first place I set up OSP in octo mode, disabled all IRQ etc. and tried to write one byte...
Hi,I have an application that has one main controller that will talk to four (4) battery packs via CAN.Ie 5 devices on the CAN network.I would like ALL devices to also have USB connectivity for uploading of firmware and diagnostics.Now for the crunch...
Hi, I'm using the STM32L451VC microcontroller. I'm trying to measure the analog input with an internal ADC (12 bits resolution). The value is compensated with the vrefint (1.21V) of the microcontroller, following the next formula: Vchannel = (3 V · (...
