Recent technical history of Micro-3 firmware

There are two types of firmware in the Micro1401-3: software and hardware. The software firmware is the program code that tests the Micro1401 when you switch it on and that then obeys instructions transmitted from the host. The hardware firmware includes controls for components such as the ADC and DACs, the clocks, the digital input and output, and the host ports.

Revision 06 - Freely down-loadable now.


Date Revision Summary
11/15 06 Monitor 5

FPGA 6

  • This increases the reliability when the Micro is used as a slave in a synchronised array of 1401s.
04/14 05 Monitor 5

FPGA 5

  • When you add a 64-channel top box you have the option of keeping the original 4 motherboard channels as 0-3 and running the top box as 4-67. However, before version 5 of the monitor and version 5 of the FPGA, channels 64-67 did not work. If your top box is set to replace the motherboard ADC channels, there will be no difference in functionality.
02/14 04 Monitor 4

FPGA 4

  • Corrected readback of synch state.
06/10 03 Monitor 4

FPGA 3

  • Fixes an occasional spurious clock 0 and 1 self test error.
11/09 02 Monitor 3

FPGA 3

  • Does not load the FPGA on a warm boot if already loaded.
  • USB code rewritten to use a 4 endpoint interface.
  • ROM,F,C,n will accept values of n from 2 to 9.
  • Flash programming protects against failure caused by the MMU tables moving.
  • Support for logical ADC channels added and used to add support for the ADC64 topbox.
  • DAC silo support and test code added.
  • USB code has watchdog to detect and react to idle.
06/09 01 Monitor 1

FPGA 1

  • This is the original version.

Privacy policy

CED, through this site, does two things that relate to privacy. We would like to explain them.

Emails from down-loads

We offer free down-loads of many files on our site, from test programs to complete install files for updated versions of major packages like Spike2 and Signal.

When customers wish to take a down-load of a major package, we ask a few questions, including their name, email address, the serial number of the software for which they seek an upgrade and whether they would like an automatic email whenever we update the product. This information is emailed back to CED when they access the final down-load screen. Within this email, your browser transmits the type and version of browser you are using, and the screen resolution you are running.

The reasons why we take and keep this information are that it is useful for our software development team to know who has taken the latest versions, and it is useful for our web site development team to know which browsers people are using to view our site, and what resolution they have their screens set to.

Cookies

When people down-load a major package, we try to write a cookie, a small file in your computer, that records your name, serial number of the software package, and the version you are down-loading. These files have a lifetime of one year.

The reasons for storing this information are firstly that if you ask for another down-load some other time, your details are read from the cookie and are pre-written into the form, to save you looking them up again. The other reason is that next time you access our site, your browser looks through your CED cookies and compares the versions down-loaded with the latest version numbers read from our site. If there is a later version of a product you have already down-loaded, we tell you on the home page screen, so you know that it is worth going to the down-load page again.

None of this information is ever given to anyone outside CED. ×
