With one or two exceptions. I'll put together kits for the display driver. I can even have a few of them built for those who want a finish product (my daughter-in-law is a stay at home EE who needs

Yeah it doesn’t work very well for Capacitors or Inductors because the test frequency is so low… but I like the size… Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ

I ended up buying the FNRISI tweezers also. A note of caution.? Some capacitors read quite low from auto. When I played with the measurement frequency, things were better. -- Regards Phil VK2KKZ

Dave, I tried the same several years ago. To my understanding the TFT_eSPI library is highly optimized. It uses the DMA mechanism of the STM32F103. The STM32F401 has a different DMA and appropriate

Thanks - a good suggestion I will put my oscilloscope on the clock lines of both boards and then try the fequencies you suggest - will post soon to say how it goes. 73 Dave GM4NFI

Mark, just remember, for troubleshooting… all you need is the Main board, the RF board, and the display… you can take everything else out of the chain (eg RX antenna straight to the RF-in on the

I have used the Atlas LCR for years to sort SMD parts. You can get Tweezer probes off Amazon (I think) and adapt to any LCR meter. Tim W4YN

Hey yall, I've built my boards and have them all hooked up.? I've started with receiver checkout, and unlike my V11 which was amazing !, I have a lot of noise, specially on 40M.? I'm not in an ideal

I have one of these too… makes removing SMD parts a snap (mine is a different model). Soldering tweezers. Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ VP2EHZ Owner -

Thanks Greg! I've been looking for something to measure SMD parts. dave, n3ds [email protected]> wrote:

Thanks! Just bought one. Looks like a reasonable tool. Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ VP2EHZ Owner - Operator Big Signal Ranch – K9ZC Staunton, Illinois

I have the FNIRSI tweezers: https://www.amazon.com/dp/B0DBQ4SQGK Pretty good!? Nice to have on the bench during assembly to double-check things. -- 73 Greg KF5N

Sorry, missed your comment... from the usermanual in the Amazon link. They are what they are, but for a ball park figure, perfect. I'm tempted to makeup a lead so I can use the tweezers with my rather

The two boards have a different clock speed (84 vs 72MHz).? It appears the spi frequency for the board can't be set to the 36MHz as is being done at the bottom of Setup32_ILI9341_STM32F103.h. Try

I have been using STM32F103 BluePill boards for several years without any major issues and have them driving ILI9341 TFT displays OK. I decided to try/experiment ?the STM32F401 and have a bought a

Ok thanks. I see what went wrong… that section was copied straight out of the BPF manual and unfortunately not updated. I can fix that. Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ

The assembly manual T41_RF_Board_Assembly_Manual_V12_042324.docx was confusing in the following paragraph which I understood to say, use address "100": Thanks for all you do on this project. I am

You are quite welcome Dave… For feedback, which documentation is lacking to help avoid a problem here? Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ VP2EHZ Owner -

That was it!!!! Wrong address. Now all three boards work with varying receiver attenuation. Now I'm on to calibration. Thank you all for your help. dave, n3ds [email protected]> wrote:
