When you say it isn't toy .. what makes it not a toy?
The price, I think.... I totally agree with you about the pricing policy of JLink.
I am also using BMP with Eclipse and gdb and it is OK.

Re: ST-Link Vs Jlink

Original JLink is not a toy... costs about 300$ for basic version and 500$ for Plus, it is unfair to compare it with the ST-Link. Actually ST-Link is an ISP interface with some debugging abilities and JLink is a professional JTAG.

Re: ST-Link Vs Jlink

Personally, I found BMP more convenient than others. I like also the embedded usb to serial interface. For professional use, specially for debugging, I think that JLink is the way to go, as it is the industry standard and is officially supported (eg. Eclipse, ARM plugin, etc...). For hobby use, and ...

Re: ST-Link Vs Jlink

and the Black Magic Probe.... (aka BMP) Is another type of SWD adaptor but... - It is open-source/open hardware. - Includes debugging functionality as gdb server ( replaces stlink+ocd ) - Includes an UART interface - Supports non STM chips. Actually you can transform to BMP any STM32F103 board with ...

Re: Rogers postbag

Roger, watch the video of Andreas Spiess about small solar chargers, you will find measurements for most common modules, is a very good review.

PS. Dont forget to watch and the second video of review : https://youtu.be/ttyKZnVzic4

Re: BMP bleeding edge binary for bluepill

Thanks Rick.

BMP is very convenient, I am using 2 Bluepills on a breadboard, one as BMP and the other as Target, with just one USB cable I have everything... very nice!

Re: Can you "break/burn" the i2c ports?

I have used many times this small screen with Blue Pill without problems, but always with Pullup resistors and voltage shifter. Pins PB8 & PB9 are 5V tolerant so there is no fear to burn them with 5V. If you want to test the circuit fast, put at least pullup resistors 4K7 connected to 5V and try aga...

Re: Can you "break/burn" the i2c ports?

First you have to use 2 resistors (2K2-4K7 value) connected to each of I2C pins to 3.3V

In your circuit you are using this display which is 5 Volts logic, normally you have to use a proper voltage shifting circuit as pins of STM32 are 3.3V.

Re: Hello there (Nafpaktos / Greece)

Use a cheap ST-Link interface (or the STlink from a nucleo board) or a Black Magic Probe with blue pill, anyway using SWD for download (and debug) it's much easier. You can also transform a Blue Pill to Black Magic Probe very easily. Always I had problems using bootloader with USB CDC... (no consist...

Re: Making your own pcb's.

My concern about halogen ovens is about stability (eg. vibration) of rack inside oven and how this affects the pcb. For reflow I have used an Electic Crepe Maker (hot plate actually) with very good results. Crepe Makers have acceptable flatness and temperature distribution.
