And the not so great photo of my setup is in the group Photos section: /g/HBTE/photo/0/4?p=Created,,,20,2,0,0 Parallel PE4302 pins are on one side of Nano, SPI pins on the other side.

I already posted it.. but I can't find it either.? Erik kind of hid it in the code? ;-) const int SI_nSEL[4] = {6,7,0,0};? //gaw changed??? 2? LEVEL SHIFTERs const int SI_SCLK = 10 ;??? //

Pin numbers you should be able to figure out from the code from any instance of "pinMode()". For example, in Erik's original code: ################### const int SI_nSEL[4] = { 0,5, 11, 12 }; // #4 is

Gary, After a little bit of cockpit errors (mostly selecting the right board support package and getting the Nano programmed) I got the Nano set up. In my case I had to use the following settings to

Glenn (VK3PE) and I have been cogitating building the SA using an ESP32. I might suggest?for that processor, try the TFT_eSPI library ( https://github.com/Bodmer/TFT_eSPI ) for the ILI9341 display.

Gary, WOW..! Thank you posting that sketch..! This will give me the ability to construct and test my hardware until I can use the 'Blue Pill' board to add a local display. What I've come to learn on

Since I haven't gotten all my hardware to build Erik's TinySA, I thought I'd start testing the GUI/touchscreen with different MCUs and Touchscreens to make a stand-alone SA using the Arduino IDE.

I have posted my Nano version of Erik's code in folder WB6OGD. The local display and encoder are turned off, you do all control with Erik's PC program. Erik set up his code so you only make minor

I believe those using a Nano had to strip out the display and encoder stuff. Yes, pins are very different between the Nano and the Blue Pill, but any digital GPIO pin should work. Search the code for

Jerry, What's rfeally odd about this is that the .ino file I'm using is the same one from the file area on this forum for the tinySA (tinySA.ino) and just by compiling it with the required display

Using up all but 74 bytes on a Nano for global variables is a very bad idea. You will almost certainly run out of RAM, given all the C++ cruftiness out in the Arduino libraries. Your only clue will be

You want suggestions? Here's one: /g/QRPLabs/topic/69666632#42281 Many of these parts are quite small, I'd be hard pressed to get by without good optics. Otherwise, tough to know if

Well...Since I am having no luck getting the Windows drivers working with my 'Blue Pill' board, I switched over to the Nano and attempted to compile and upload the tinySA.ino sketch into my Nano

Joerg, I was able to use my ST-LINK V2 programmer to get the 'generic_boot20_pc13.bin' into the 'Blue Pill' board - that went fine. However, I'm stuck with the Windows drivers for the USB port. I did

I wound up ordering these: https://www.ebay.com/itm/EPCOS-433-92MHz-SAW-B39431-B3740-H110-BW-360KHz-3-0x3-0mm-10pcs/163839895135 (the seller kindly added the matching network performance data in an

1st post,??? the specified filter appears to be obsolete and hard to get in VK at least. I found this part at RS-components.com? "RF3446E"??? BW appears to be just whats needed. Approx 1MHz.?

Im not 100% certain, but I seem to remember reading somewhere that you have to create a .bin file and use an external bootloader for that processor. -- John P. WA2FZW

Marty, it is quite some time ago, that I bought my blue pills. But as far as I remember, they do NOT come with the Arduino bootloader. Initially you can only upload programs using either a separate

Joerg, While I'm at it, the Blue Pill board is programmable through the USB port to upload a sketch, isn't It? Mine is fresh from Amazon. In the IDE environment, which board settings do you use to
