M41T81S RTC chip. Remembering time on power down.

Posted on October 28, 2017 at 00:57I am using M41T81S chip for a RTC.I am having a issue keeping a time on power down.I borrowed the circuit from following location.http://www.niell.org/nixie_3/NixieClock5-1.bmp Instead of C2 in the picture, I am us...

STM32L476RE: Can I have two timers (TIM2 and TIM3 for example) using the same external clock source?

Posted on October 27, 2017 at 00:54I need to create two synchronized signals. I'd like to use a PWM output for one, and to have the software create the second signal based on an interrupt from the same clock used to create the PWM output.I'd like t...

STM32L1xx: changing interrupt priorities during interrupt - effects?

Posted on October 23, 2017 at 13:54On an STM32L100 series MCU: Assume that initially, Systick priority is set below EXTI15_10During the EXTI15_10 ISR: Systick occurs, but its interrupt is held because we're in a higher-prio interrupt;I then chan...

ST, don't use / / for one line comments

Posted on October 26, 2017 at 22:43 Because IDE does not like nested comments. I am commenting several lines of example code but some idiot has put every other line an one line a /* */ comment. Fix that software please. Not like this: /...

Resolved! STM32F303 Nucleo-144: which IDE to use for Development?

Posted on April 06, 2017 at 13:36Hi,I have a STM32F303 Nucleo-144 Development Kit and struggling to figure out which IDE to use. This is first project with Cortex-M micro-controller and I have a few queries:* If somebody who is aware of the software...

Resolved! CY62177EV30 SRAM with STM32L496AEI

Posted on October 19, 2017 at 09:53Greetings people,I was wondering if the SRAM by CY62177EV30 is compatible with the FMC on STM32L496AEI with 20 bit address width and 16 bit data width.I can only use 20 bits from the address bus because of pin mul...

Boot from SRAM

Posted on October 23, 2017 at 10:49I have a question about the stm32f103xx. I want to know how it boots from Embeded SRAM. I have known that the IBUS of Cortex-M3 can't access the SRAM from the reference manual. When boots from the SRAM, how Cortex...

Disable STM32F103 Independant Watchdog

Posted on October 19, 2015 at 11:01Hello,In one of our projects we have implemented IWDG (independant watchdog). There is a condition in the software that when the power supply fails, the controller STM32F103(Powered By Rechargeable Battery) puts it...

nucleo board communicate with raspberry pi through SPI

Posted on October 27, 2017 at 14:57the task is to make nucleo board L476 to commucate with raspberry pi 3 through SPI. Now the code on both sides are finished and build successful. But I don't know how to test if the data are sent successfully. Is t...
