Now you will set up the state of all the unused CPLD pins. Requiring 2 programmers is a pain. Step by step guide. So you can decide to upload the new sketch at first with the new “scenario”, but in this new sketch a STM32 pin will be changed as an output, so you have two output connected together too! Adobe Portable Document Format – In this way is easier to set up a complete “test bench” for the CPLD “application” e. In the following we will examine this sketch too.

The complete Quartus II project can be downloaded from this file: Become a member to follow this project and never miss any updates Become a member. The “pluggable” LCD module and the optional stand-alone 50MHz oscillator aren’t included in the cost count. Already have an account?

In this way datsaheet can simply “freeze” the CPLD holding the configuration inside. Some important notes about these two function: Now it is necessary to add a schematic sheet into the project. From the above windows, on the left side, choose ” Unused Pins “: Step by step guide”. Fill the directory for the new project, and the others names.


In the back side there is a short note on how use the solder jumpers. In this case you need to populate C31 and C35 too see the schematic. This is an other unique “feature” of this board. This one is for the read operation to check the four USR buttons status: The result is shown in this short video: Now you have an empty template and it’s possible change the setting.

These are two important functions: The internal digit registers are now 8 bits wide, because now each single segment can be controlled plus the “dot”and there is a 4 bits register for the four leds LED Two dev boards into one.

Description Two dev boards into one: This setting must be used for every new project, so in the following we’ll see how to create a new project and apply the correct setting.

View all 8 files. Form the designer tool bar select the ” Symbol Tool “: The behavior is very similar to a SRAM device. Sign up Already a member? Similar projects worth following. I’ve just finished the new PCB revision: View all 8 project logs. dxtasheet

This is a ready to use example of a custom controller for a 4 digits 7-segments BCD led display. Now what it can happen if you want change, for any reason, an input as output and an output as input in the same change?


And a short demo video: This is the environment: You should Sign Datsaheet. Your Email Remember me.

EPM (Altera) – JTAG & In-System Programmability

About Us Contact Hackaday. Now some more checks before send the files to the PCB service Does this project spark your interest?

Here it is the schematic editor with the loaded project: Now save this project. The custom controller has four registers to store the BCD digits, darasheet drives a 4 digit BCD led display already assembled on the board with a BCD to 7-segments decoder using multiplexing. I remember the data sheet had the pin functions on the left and the pin numbers for various packages on the right. I suggest to use the same name for all the fields as done in the photo. Well, if you update the CPLD configuration at first, the new configuration will change an input as output, so this can generate a short circuit between the CPLD and the STM32 because there would be two output connected together.

As far as I know, there is no commercial product that has this epn570. An optional on-board 50MHz oscillator is available too not assembled in the previous photosand there ratasheet also two connectors for external oscillators.
