"title": { The OE pin is used to read data from the chip, and the CS pin is used to select the memory chip itself. ShopifyBuy.UI.onReady(client).then(function (ui) { "color": "#ffffff" "button": { The address and data for the EPROM (ZIF SOCKET) are set by using DIP switches SW1 and SW2, respectively, whose pins are initially pulled high via 10-kilo-ohm resistors. This is the EEPROM programmer I built to connect the chip to my desktop computer. For example, if we want to send the byte 0xFF, we instead send the ASCII characters FF. It’s a very simple, low-tech project … but has attracted a consistently-high number of visitors to the site and is something I use several times a week.
