RadASM 3.0.1.0 for STM32F103C8T6 MCU (Blue Pill)
« on: August 05, 2022, 06:32:47 PM »
I have uploaded a complete RadASM package to Sourceforge so you can quickly get started programming this clever little MCU.
It includes the gcc compiler so the download is almost 300MB.

Supported boards:
STM32F100 Discovery
STM32F103 BluePill
STM32F401 BlackPill
STM32F407 Discovery
STM32F411 BlackPill

New boards can be added.

https://sourceforge.net/projects/radasm30/files/RadSTM32/

Unzip to C:\RadSTM32

The package also includes STMSpy. It gives you easy access to documentation and debugging.

You can buy the device on Ali Express
https://www.aliexpress.com/item/1005003880238896.html

You can download RadASM30 release and sources here:
https://sourceforge.net/projects/radasm30/files/Release/

Let me know if there is any interest in this project.

I am currently working on a portable all in one electronics instrument.

o LC Meter. Measure inductors and capasitors.
o Voltmeter. +/-20V
o Logic scope. 4 bits logic analyser, 15K sample buffer,  1Hz to 20MHz sample rate.
o Wave generator. Sine, triangle, squear and sawtooth, 100Hz to 10KHz.
o PWM Output. 1Hz to 20MHz.
o DDS squear wave. 1HZ to 1MHz, 1Hz resolution.
o Scope. 10MHz at -3db.

It is just incredible what yo cam nake with this MCU. :biggrin:

The zip contains some images.

Hello Ketil,
You have upgrade RadASM from 3.0.0.9c to 3.0.1.0, thank you.

Did you update the sources that you provide here:
Code: [Select]
https://sourceforge.net/p/fbedit/code/HEAD/tree/RadASM30/RadASM30/

I have checked the dates of the sources but they seem not updated?

BTW, i have ordered a new STM32F103C8T6 and waiting for it. Thank you!

I'm very curious about this project; the pictures have whetted my appetite. Any more info on this? Schematics?

Interesting, thanks.

But I don't see some things: the display, and the L and C measurement circuitry. (Interested in that latter thing; I built a L-measurement attachment to a DVM that works pretty well. Would like to be able to at least ball-park measure L and C.)

Hi,

Someone else designed the LC meter.
You can find it here:

Thanks again. Sorry to complain, but they say

Quote
... programmed PIC16F628A microcontroller ...

so no code, have to buy their chip. Not totally DIY. That's a different MCU from yours, right? Did you program your own?

=========================================================

Ackshooly, not a bad deal for $30: ESR meter/transistor tester/LC meter all in one ...

Hi

Just ignore the pic and display. Only the analog part is used in my project.

Included ar all the schematics and pcb design. Note that the lcd and push buttans are on the back side of the pcb.
Also note that the connections to the lcd might be different from the one i am using.

NOTE
This is only the prototype to test my design. When everyting is working and well tested i will design a single pcb.

Hi,

 The RadSTM32F103C8T6 package contained the STNBuild.exe file.
Recently Windows reported this as a virus.

You should delete the whole package and download and install the new RadSTM32 package:

https://sourceforge.net/projects/radasm30/files/RadSTM32/RadSTM32.zip/download

See more in the first post.

I have created a SimCad addin. It lets you create and edit simcad files  (*.cad simple drawings) in RadASM30.

Copy the unzipped files to the Addins folder.

OP amp offset and PWM output error correction.

Digital voltmeter:
------------------
Short the inputs.
If you dont get a 0.00V reading the offset must be corrected.

If the OP amp and PWM has no error
#define DVM_OFFSET_ERR 2048
If you have a positive reading, decrace the value.
If you have a negative reading, incrace the value.

TIP:
First program the device with the value 2048.
If you get a reading of 0.34 then subtract 34 from 2048
and reprogram the device.

NOTE:
The accurancy of the voltmeter is dependent on the 3.3 volts
regulator. If you have more than one STM32F103C8T6 then choose
the one closest to 3.3V.

Digital oscilloscope:
---------------------
Short the inputs.
If the wave line is not in the middle the offset must be corrected.

If the OP amp amd PWM has no error
#define SCP_OFFSET_ERR 0
If the line is above middle, decrace the value.
If the line is below middle, incrace the value.

Overshot / undershot adjustment.
Select CAL.
Connect the probe to DDS wave out (PC13).
Adjust the 40pF variable capacitor until you cet a flat top.

              |\_____
Overshot      |
              |

                _____
               /
Undershot     /
              |

               ______
              |
OK            |
              |


LC Meter:
---------
Leave inputs unconnected.
Select Calibrate and change LCM_F1 and LCM_F2.
#define LCM_F1 494572
#define LCM_F2 352336
