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...
Posted on August 26, 2017 at 16:06Hello 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 i...
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 ...
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...
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...
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...
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...
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...
Posted on August 25, 2017 at 05:45I got my new board, When I want to download the .hex file, I tried to use the keil 5.14 and ST-link utility ,failed.the message I got from the ST-link utility is:Can not read memory? Disable Read Out Protection an...
Posted on August 24, 2017 at 22:39We're going to use a Nucleo-L433 board in a prototype. The boss wants to know whether it can be reflashed - but after the debugger board is cut off, to save space.Can it be done? Thanks John#nucleo-32l433-flash
