There is no reason to use a fancy Maxim chip for an LED display. Two
74HC595 SPI shift registers and two 74AC245 octal buffer chips will do the
job. One for the anodes, one for the cathodes.

That’s a lot of clocks in a short time! I particularly like the third and
seventh clocks.

Well done Christine, you certainly grabbed the bull by both hornsreally
nice clocks! Thanks for sharing.

The Maxim part you mentioned is for VFD's, and it looks like it can run as
low as 8V. If you use it to drive the anode of your LEDs, you run the risk
of exposing the logic driving the cathodes (segments) to roughly 6 volts
(the LED has about 2V of forward bias).
If the Arduino has 5V-tolerant
Hi,
I am sure the group can help with this simple question. I am building a
clock using 8 x 7 Segment Common Anode
displays. The display uses a MAX6921AWI display driver chip and
multiplexing to drive the displays. The
problem is that the above chip has a minimum output of 8V, however the 7
So now the true reason for the delay reveals itself! Again, sorry for that;
a customs check just seems to be the luck of the draw.

Hello, yes, I just got the same notifications and now Parcelforce in the
UK seem to be accepting ownership!
My friend in HK is very pleased with his and has been sending me pictures
of it all afternoon which has been fairly depressing - until now!
Lets see how long it takes Parcelforce to work
Richard,
Good news, looks like there was a new scan today. Package should be on it's
way!

Switching to the ESP32 was frustrating, but well worth the trouble. I just
use the ESP32 DevKit C and Pico. Can't beat it for $10, and it has built in
USB. I designed my own clone of the DevKit C to play around with reflow,
but the parts cost was around $14 so not a good value
