USB на регистрах: STM32L1/STM32F1. С программным USB на примере AVR мы уже познакомились, пришла пора взяться за более тяжёлые камни — stm32. Подопытными у нас будут классический STM32F103C8T6 а также представитель малопотребляющей серии STM32L151RCT6:

そうそう、秋月電子でSTM32L1のDiscovery買いました。

CubeIDEはSTM32L1に対して何を設定してもEXTIのHALドライバを生成しない。一方、ほかの製品に対しては何もしなくてもEXTIのHALドライバを生成する。. 3年前にレポートしたが放置されている。ということは、ST社員を含む誰もこのドライバを使っていないんだろうな…。

Today's goals!.rode to ueno, checked out this dodgy shop for @MangaMogura , oh boy if you like plastic vaginas, this is the place for you. mooched in Akiba, bought an STM32L1 Discovery because it was cute. I guess they are the precursor to the NUCLEO series.

That's why I love #stmicroelectronics. Dropped by their booth at #spsipcdrives, mentioned my #stm32l1 project and immediately got advised on a cheaper and better controller (the #stm32l4). A #stm32nucleo board also was complimentary to help me…. 📸

STM32L1 微处理器用130nm的工艺，L4用90nm的工艺。其低功耗特性把一众国产40nm甚至22nm的MCU打得跪地求饶，闻风丧胆。. 德州仪器曾经声名赫赫的MSP430系列也自叹不如。. 大家感兴趣的话我可以聊聊这个。

#stm32 #debugging is easy with #atollictruestudio aka #stmcube_ide. Remove the two #jumpers from any #stmnucleo board, and connect the target. No #zeroohm resistors need to be unsoldered or anything - my #stm32l1 debugging experience was flawless.…. 📸

New #stm32 family. The #STM32H7 is a #cortexm7 #armprocessor with a max #clockspeed of 280MHZ and the usual advanced #lowpower modes #stmicroelectronics debuted on the #stm32l1. STM's pressrelease emphasises the large 1.4MB RAM, which should make…. 📸

#lowpower #microcontroller programming is notoriously nasty - need to get up to speed with the #stm32l1 for a small project related to my #cigarlife. Russian web site #habr has a nice story on the topic, which was translated by someone and can be…. 📸

#gd32l233 family is NOT intended as a #pincompatible replacement for the #stm32l4 / #stm32l1 / #stm32l0 / #stm32u5 or any other low power micro on the market. Any such rumors in the market are wrong! The #GD32L2 is intended to be used in…. 📸

STM32のHALってのは存在しなくて、STM32L1のHAL、STM32F7のHALって感じにシリーズごとにHALが存在している。. 搭載しているペリフェラルがちがうって？それがSPIだのI2Cでも微妙にAPIが違うんだよな。. Hardware Abstractionとは。.

Apple Pencil 2 Firmware.====================.accel - unknown non ARM MCU.charger - ARM based MCU - might be STM32L1.mt - ARM based MCU.radio - ARM based MCU - seems to be nRF52832.stylus - ARM based MCU - seems so be STM32L4. Interestingly @ifixit did not find these in teardown.
