Resolved! Schematic for Nucleo-L412RB-P please.
I'm trying to find a schematic diagram for the Nucleo board with the L412 processor, but can't track it down. I've looked in the User Manual for this product (UM2206 rev 5) where I would expect it to find it but it isn't in there. I'm not sure if thi...
Resolved! Why there is no USB connector provided for USB FS peripheral in STM32F769I Discovery Kit?
So I bought STM32F769I Discovery Kit but only to find there is no USB connector provided to access the MCU USB FS peripheral. It only provide for USB HS, why so?How can then I do verification on the USB FS peripheral of the MCU?
Resolved! Official STM32 Nucleo-64 schematic diagram?
Hello there,I'm looking for an official STM32 Nucleo-64 development board (probably mb1136) reference schematic diagram. So I can design my own product based on that.I found some schematic on Digikey and Arrow or my team can also do but it would be g...
Resolved! Unable to program using ST-Link
We are using STM32L476ZGTx. Until recently I was able to program the chip using ST-Link. A few hours back programming failed due to power issue and since then I have been unable to program the controller.The device connects with ST-Link Utility every...
"No STM32 target found" on consumer device
I'm trying to use a ST-LINKv2 to re-program a consumer device that I know has an STM32 of some kind inside (fairly sure it's a STM32L-something). I found four headers on the board that a continuity tester has shown to be Vdd, Vcc, SCLK, and SWDIO.Con...
problem arising while connecting more than one Relay
Hi, i am working on a project where i am using 4 Relays. once i Set any one of the relay the voltage and current should flow to a particular Relay and it should turned on and off. But in my case all the four relays will set and reset . if i turned o...
Nucleo H745ZI-Q drawing current spikes from USB power port - producing noisy 5V
I have a Nucleo H745ZI-Q board powered from the CN1 STLINK USB port. I am observing bursts of noise on the 5V line. The noise is 150mV p-p, burst of about 6 (80us) pulses, every 18ms.The H745 is idle and the debugger is not active.I have tried severa...
Resolved! what debug tool can be used with stm32h747i-disco board?
There is a 4-pin connector for ST-Link, but not populated. What debug tool can be used with ST-Link-V3E connector (micro USB)?
Resolved! Error in initializing ST-Link device. Reason: (-1) Unknown. Please check power and cabling to target.
