The JEM-EUSO program aims at detecting Ultra High Energy Cosmic Rays (UHECRs) by observing the fluorescence light produced by extensive air showers (EAS) in the Earth's atmosphere. Within this program, a new generation of missions is being built, including (i) Mini-EUSO that will be installed on board the ISS in August 2019, (ii) an upgrade to the ground-based telescope EUSO-TA and (iii) the second super pressure balloon flight (EUSO-SPB2). All these detectors will have a dedicated trigger system based on a board equipped with a Xilinx Zynq device that will be able to detect different types of events on three different time-scales: a microsecond timescale for cosmic ray detection (L1), a hundreds of microsecond time-scale for slower events like transient luminous events (TLEs) (L2), and a tens of millisecond time-scale used to produce a continuous monitoring, for even slower events like meteors or nuclearites. The L1 trigger logic for the upgrade of EUSO-TA and EUSO-SPB2 are being developed taking into account the peculiarity of each detector (optic system, FOV, frame length) starting from the logic already developed for Mini-EUSO. In particular, every pixel will have an independent threshold that will be dynamically adapted to the level of the background; a predetermined condition on the number, the position and the time distribution of pixels above threshold has to be satisfied in order to issue a trigger. This contribution will summarize the L1 trigger logics and the tests currently performed.
