SN74HC595 Multiplexed 7 seg LED display
A simple display (4 digit) using a shift register. A couple of points: 1) Pull the OE (output enable) pin to ground either in code or in hardware. 2) Multiplex needs to be called regularly - ideally use an interrupt - as per demo. However it could be called in a loop (with a delay). Something like 2...

Re: SmartScope Offer
Keyboard shortcuts are my go to option
Though otherwise 'goto' is frowned upon!

Re: SmartScope Offer
Shiny...
Mostly it's intuitive - or becomes so?
I've never managed the signal generator though - one day i might have the need.
It's designed for a touch screen interface - works well on Android - I often run on tablet.

The 'trace' showing the 'common' pins.

Re: 1x 74HC595/TPIC6B595 via SPI interface, driving multiplexed 4x 7-segment display
Pins for CA0 (probably should be CA1 ?) - CA3 etc are in properties. It's all Flowcode - but doesn't attempt to simulate (although you can look at what is being sent to the shift registers and the common pins in multiplex)

Re: 1x 74HC595/TPIC6B595 via SPI interface, driving multiplexed 4x 7-segment display
I had a play with this... This is a first idea - and as Iain says using CS as RCLK seems to work well... I use an interrupt to multiplex the displays - the character set is a rough attempt with QA connected to segment A, QB to seg B etc) I found an interrupt rate of 244Hz worked nicely (each digit r...

Re: ESP32 Firmware Protect
I've not encountered any - I'm currently using v5.5 - and so far no problems... There have been issues with installing versions - which, luckily, i seem to have avoided - I've always found running the online installer and then the install.bat (in the framework directory) had been good - but back eve...
