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...
Hello,my intention is to catch a 'thin spike' from the input analog signal. Therefore I wish the sample times from 2 ADCs may cover echo other's conversion time, so that the thin spike will not be missed.My plan is to use 8.5 cycles for sampling and ...
Hello,I don't understand the description of the Clock Security System in the Ref Manual of STM32H7 (section 7.5.3).First question is : what exactly is the CSS doing ? (what kind of control is done on the clock). What is a definition of "a failure of...
I followed the getting started tutorial, when I pressed the reset button then the user button, the uart terminal indicated failed to provision certificate -1 as the attachment. Could you some tell me what's the problem
Posted on July 07, 2018 at 04:41Hi, I'm having trouble reading a register in a slave through I2C communication. Slave: bq25895 http://www.ti.com/lit/ds/symlink/bq25895.pdfIn main:while (1){ HAL_StatusTypeDef status = HAL_OK; uint16_t return_val...
the DAC1 out1 working fine as programmed bt DAC1 out2 is not. Is it due to bridge18 A4 to D4, should I remove bridge. I try setup D4 as Analog and Digital IN and does not helped. Is STN32L$#@RC damaged on out2?
Hi,I have a single adc channel where i read the input values through polling, but it always outputs the max value or almost max value (~ 65280+) as long the input voltage value is greater than zero (v0.5+ ). i configured VREF+ to internal voltage ref...
The 'F427 (437/429/439 "BigManta") is pretty much completely backward compatible, meaning, that a reasonably well written 'F405/407 program (i.e. which does not touch the bits reserved in 'F405/407) binary will run unmodified in the 'F427. There are ...
Hello,I am trying to erase/flash program an external W25X40CLSNIG flash chip with various STM32L4xx host chips using SPI protocol. Up until now I have been referencing STM32l4xx_hal_spi.c source file for ways to perform such a task but was curious if...
I am using ADC1 and ADC2 of STM32F446RE, which are operated under the following conditions;Dual ADC modeRegular Simultaneous modeExternal triggerI can correctly read the converted values through ADC1->DR and ADC2->DR.However, I can not read the corr...
The SWO/TRACESWO with Instrumentation Trace Macro cell should be able to extract information about what instructions or addresses were executed.However I still can't find the right tool to do it.It would be enough for now to show the addresses the PC...
