I went to the site and saw your message, your letter got into spam (((.
Try to increase the capacity after a 3.3 V stabilizer and apply voltage to the input. Vin = supply voltage 12V

Zbyszek, to synteza MICROB4 bez żadnych dodatkowych "Bajerów" z procesorem stm32f100cbt6b.

Yuriy thank you for your answer.
Your suggestions didn't help, but the synthesis works with old software "synthesizer__microb_v4_10102017.bin. Both newer versions from 2018 don't want to work.

73! de Jacek.

Did you upload firmware for F100? Because there is a firmware for F103.
The latest firmware for 2018 is all working, it has been tested many times.
I recommend using it.
synthesizer_stm32f100cbt6b_microb_v4_27122018.bin
Make sure you have a controller with 128kB flash on board.

I want to warn. Not all that is written is true. Here I have such a copy. It is written F100 and in fact it is F103.
Thanks to the Chinese brothers!

Yuriy, you are probably right. I guess I've some "painters" - only which ones?
Works soft for f100cbt6b (only ver. from 2017) and f100c8t6b. others don't work at all or don't save menu changes.
I'll leave the 2017 soft because the PCB may not withstand the next CPU change.

Thank you for your help,
73! de Jacek.

There is a suspicion that you have a 64kb flash controller.
Read on the body of the microcontroller what is written, each char is important, and write to me.

128 kb microcontroller. exactly what is needed.
Questions.
What voltage do you apply? Pin Vin input must be connected to the positive voltage that is supplied to the synthesizer.
In the system menu, the option "Low Voltage" is values set?

What is the capacitance of the capacitor after the stabilizer 3.3v microfarad?

try this firmware for today's date synthesizer_stm32f100cbt6b_microb_v4_19022019.bin

" Pin Vin input must be connected to the positive voltage that is supplied to the synthesizer."

I've missed this information before. Now it's working properly.
It's good that processors are not expensive ;-)
Thank you very much Yuriy.

Yuriy, Is it possible to add 60m band to the Microb4 menu?
