Firmware library for the L6482
Hello, I've been using the L6482H discovery board and have got it to work ok. Now I want to control my EVAL6482H board with a nucleo F072RB board but I'm not sure how to proceed.   I tried to download the STSW-SPIN005 firmware library for the L6482 but the link is broken. I've gone into my dSPIN discovery kit > user_motion > dspin and found… (Show moreShow less)

STM32 ST-Link Utility - bug?
I use a debugger of ST-Link and STM32 ST-Link Utility, I try to read 128K of the microcontroller flash-memory from the address 0x08020000. But STM32 ST-Link Utility reads only to the address 0x0802E000 - further the utility shows that memory is empty. But actually in memory there are data. It is a program error?

What part exactly are you using? Does the code appear to be at 0x08000000..0x0801FFFF ? Does program/verify indicate an issue?

Auto Wake-up for STM32F042
Hi everybody,   I'm wondering why the HAL library does not allow to program an auto wakeup for a STM32F042.   It is not allowed via CubeMX GUI neither.   I've looked into hal files :every function used to init/use the auto wakeup are surrounded by : #if defined(STM32F070xB) || defined(STM32F071xB) || defined(STM32F072xB) ||… (Show moreShow less)

hi,   i am using STM32F401RBT6 (LQFP64) and i can't connect ST-LINK/V2 ISOL (FW V2J27S6) to program my board. i always have "no target connected". i tested with SMT32_utility and MDK-ARM. pin60 boot0 = 0, pin7 NRST = 1, pin46 TMS to ST-LINK/V2 pin7, pin49 TCK to ST-LINK/V2 pin9, pin55 SWO to ST-LINK/V2 pin13, gnd to ST-LINK/V2 pin4 and i tried… (Show moreShow less)

What is the COMP2_INM4 pin for in STM32F303C6 COMP module?
The STM32F303C6 has COMP peripherals COMP2, COMP4 & COMP6. Each of these comparators have a positive (INP) and negative (INM) input pin and an output (OUT) pin. Furthermore the data sheet specifies for each comparator a pin named INM4. I am wondering what these INM4 pins are for. Can somebody please tell me?   Thank you in advance, Gahlen.

Based on RM/DS reading, I'd say you still can use PA4 as negative input to one of the 3 comparators even if DAC1OUT1 is not enabled, as an input to external voltage.   jW

STM32 and STPM33 weird SPI behaviour
Hello, I'm building a multi phase power meter with 6 pcs of STPM33 ICs and an STM32.  The STPM33 chips are on the same SPI bus, with separate chip selects (SCS) for each meter. The MCU can control all of the control signals (SYN, ENABLE, SCS etc.. ). The meters are daisy chained together by the 16 MHz clock line, as the datasheet recommendation.… (Show moreShow less)

(I've opened a support ticket with ST on this issue and we've provided the following test results...) SUMMARY We removed the STPM34 chips from older prototype boards that worked fine and replaced the STPM34 chips on the pilot boards with those from the prototypes.  The pilot boards began working properly after the chips were swapped. CHIP…

Troubles flashing software on STM32f107VCT6 using FlashLoader Demonstrator
Hello,    I'm working with a proprietary board using a stm32f107 and I would like to flash my soft into the ship by using RS232. To do that I have a RS232 connector which can be connected to USB and then I can collect Rx,Tx and GND from the DB9 connector.    My trouble is when i'm trying to flash my soft with Flash Loader Demonstrator, I'm… (Show moreShow less)
