UART Receive Buffer Clear
Posted on September 03, 2016 at 00:50 I am working on STM32F0. I am little confused between USART1_IRQHandler and HAL_UART_RxCpltCallback HAL_UART_RxHalfCpltCallback HAL_UART_TxHalfCpltCallback HAL_UART_TxCpltCallback Is it necessar...
DMA Transfer Complete and USART Transfer Complete
Posted on August 14, 2017 at 13:47Hi all:I have been using DMA with USARTs for years on STM32F4xx and STM32F0xx microcontrollers, but mainly with full-duplex connections like RS-232. Now I need to handle RS-485, which is only half-duplex. My code ne...
Resolved! Hello Guys I am using STM32F429IGT6 controller.I am using EWARM. recently my code size reached 1MB so during download it gives error'writing outside flash memory at address 0x08100000'.But as the flash region is from 0x08000000-0x081fffff it should

Blue Pill external interruption
Posted on August 26, 2017 at 02:37Hi,recently I started my adventure with STM32F103C8T6. I had some experience with programming on other boards e.g STM32F3 Discovery but I came accross a problem with external interruptions. I am using EclipseStm as ...
STM32L1 + Instruction Prefetch + Voltage Scaling + Debugger = Unexpected Memory Values
Posted on August 11, 2017 at 20:44Hi, we are using an STM32L151VET device, using CubeMX generated startup code (any modifications seem benign to me for reasons that follow) and have been encountering a strange error when running with a debugger atta...
Conflicting Types for 'HAL_Init'....(w/no changes to HAL files)
Posted on August 25, 2017 at 21:00I am building a project that I've previously built with success, but am now getting the error Conflicting Types for 'HAL_Init'. Since my last build, I've only made small changes to the code for my timers and have no...
[OTG + documentation + Cube] OTG_FS interrupts in 'L4
Posted on August 25, 2017 at 21:20More.RM0351 rev.5 says thatThere's no other OTG_FS interrupt mentioned in that interrupts table. Does that mean that EXTI line 17 should be enabled to be able to receive the OTG_FS interrupts?Turning to the EXTI cha...
weakness in the signature algorithms on non-accelerated hardware in the cryptographic library
Posted on August 25, 2017 at 20:14Hi all,The signature algorithms (DSA or ECDSA) all require a random number. If this random number can be guessed, the signature becomes weak and the private key can be recovered (cf. the Sony PS3 signature affair).I...
[OTG + documentation + Cube] DOUTEP1MSK/DINEP1MSK (and related interrupts)
Posted on August 25, 2017 at 19:43More.Both L4 and F4 Cube use USBx_DEVICE->DOUTEP1MSK and USBx_DEVICE->DINEP1MSK, while neither of the RMs mentions them.Oh yes I do suspect these are related to OTG_HS_EP1_IN/OTG_HS_EP1_OUT interrupts, but thes...
