Setting up MPU for External SRAM + NOR + SDRAM

Posted on November 21, 2017 at 03:39I am working on a project based of stm32f746G EVAL board. It uses LCD controller with frame buffer in SDRAM, internal flash for code, external flash to store fonts and media, and external SRAM for RW+ZI data. Fina...

Non-volatile data storage in STM32F7 mcu?

Posted on November 21, 2017 at 14:04I am using STM32F777II mcu where I wanted to know how to store non-volatile data? I see that this controller's datasheet doesn't say it has any EEPROM.#eeprom #stm32-f7 #non-volatile #flash

Disable interrupts

Posted on November 21, 2017 at 05:47STMF4 is running and using some of the interrupts.A a new piece of code needs to be protected from all interrupts but a specific one, which has the highest priority in this application.The trivial solution: Go thr...

ADC measuring

Posted on November 21, 2017 at 20:47Hello!I want to calculate battery voltage, that connected to STM32L476RG board.I've connected ADC pin and this battery with divider (so Vbattery<Vref.adc).But I need to know how to get some factors/parameters.See ...

SPI Slave RX data shifted

Posted on November 21, 2017 at 17:02I'm having an issue with the LL SPI driver on the STM32L4 configured as SPI slave. My Tx buffer contains {01, 02, 03, 04, 05, 06, 07... }. When I read 7 bytes repeatedly from the slave using the Aardvark SPI maste...
