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...
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...
Posted on October 29, 2015 at 22:47 I have been using LCD (glass on chip) made by newhaven display for a while. They provided sample code to initialize. However the code is mostly for microchip, not for STM32 hal drive. Some people have been s...
Posted on November 21, 2017 at 20:54dear All,what is the probable reason of HAL_I2C_Master_Transmit() transmits only address?regards,Rasool#i2c #stm32f4 #master-trasnmitter
Posted on November 21, 2017 at 19:24In Cortex M3, what is the order in which the register are pushed into the stack?Which of the following orders are correct (if any)?First Order: PC PSRx R3 R2 R1 R0 R12 Link ...
Posted on November 21, 2017 at 20:52Hello,I have a problem with VBAT voltage measurement on a STM32F401VB.As can be seen in the picture below, the ADC output is correct (identical to the calculated value ''ADC Should'') in the upper region of the in...
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 ...
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...
Posted on November 21, 2017 at 20:10I am trying out ethernet with UDP. However, when I generate the files through cube mx, I am unable to get it working like they do in UM1713. I tried to compile a project, but it does not like 'ethernetif_input(&gn...
Posted on November 21, 2017 at 13:12I try to read data, using the HAL_DSI_Read function - in the Low Power mode I read data successfully, but when switching in the High Speed mode it is impossible to read data. Result of reading - an error on a time...
